The patch also fixes clause expansion for OpenMP TO/FROM clauses, which need to dereference references but not have any additional mapping nodes. (These cases showed up due to the gimplification changes in the C++ "declare mapper" patch, but logically belong next to the earlier patch named above.) 2022-11-30 Julian Brown gcc/ * c-family/c-common.h (c_omp_region_type): Add C_ORT_ACC_TARGET. (c_omp_address_inspector): Pass c_omp_region_type instead of "target" bool. * c-family/c-omp.cc (c_omp_address_inspector::expand_array_base): Adjust clause expansion for OpenACC and non-map (OpenMP to/from) clauses. (c_omp_address_inspector::expand_component_selector): Use c_omp_region_type parameter. Don't expand OpenMP to/from clauses. (c_omp_address_inspector::expand_map_clause): Take ORT parameter, pass to expand_array_base, etc. gcc/c/ * c-parser.cc (c_parser_oacc_all_clauses): Add TARGET parameter. Use to select region type for c_finish_omp_clauses call. (c_parser_oacc_loop): Update calls to c_parser_oacc_all_clauses. (c_parser_oacc_compute): Likewise. * c-typeck.cc (handle_omp_array_sctions_1): Update for C_ORT_ACC_TARGET addition and ai.expand_map_clause signature change. (c_finish_omp_clauses): Likewise. gcc/cp/ * parser.cc (cp_parser_oacc_all_clauses): Add TARGET parameter. Use to select region type for finish_omp_clauses call.
